Battery pack including an indicator circuit
View Patent ↗The invention is directed toward a battery pack. The battery pack includes at least one electrochemical cell; a case; a plate; an indicator circuit; and a battery-to-internal volume ratio. The case includes at least one open end. The plate is placed over the at least one open end. The plate includes a terminal plate, a base plate, or any combination thereof. The indicator circuit includes an integrated circuit and an antenna. The indicator circuit is affixed to the plate. The battery-to-internal volume ratio is greater than about 0.52.
1. A battery pack comprising:
at least one electrochemical cell;
a case, the case comprising a first open end, a second open end, and a sidewall therebetween;
a terminal plate placed over the first open end, and a base plate placed over the second open end;
an indicator circuit, the indicator circuit comprising an integrated circuit and an antenna; and
the integrated circuit is affixed to the base plate;
wherein the battery pack has a battery-to-internal volume ratio greater than about 0. 52.
2. The battery pack of claim 1 , further comprising a magnetic diverter, the magnetic diverter therebetween the at least one electrochemical cell and the antenna.
3. The battery pack of claim 1 , wherein the indicator circuit comprises a communications circuit, the communications circuit comprising radio-frequency identification circuitry; near field communication circuitry; Bluetooth circuitry; Bluetooth Low Energy circuitry; Wi-Fi circuitry; or Zigbee circuitry.
4. The battery pack of claim 1 , wherein the case comprises a non-conductive material, a non-metallic material, or any combination thereof.
5. The battery pack of claim 1 , wherein the at least one electrochemical cell is in electrical connection with the terminal plate and the indicator circuit.
6. The battery pack of claim 1 , wherein the antenna is incorporated within a printed circuit board.
7. The battery pack of claim 1 , wherein the antenna is incorporated within the case.
8. The battery pack of claim 1 , wherein the battery pack is selected from the group consisting of an ANSI 1604 battery; an ANSI 7.2H5 battery; an ANSI 7.2K5 battery; an ANSI 8.4H5 battery; and an ANSI 8.4K5 battery.
9. The battery pack of claim 1 , wherein the battery-to-internal volume ratio is from about 0.52 to about 0.98.
